GENERAL TREATMENT FOR RASPBERRIEvS, BLACKBERRIES 



AND DEWBERRIES. 



Cut Out the Fruit Bearing canes after the la si piclcing has been 

 made. This will lessen insect and disease trouldes tliat may be liarbored 

 on the old canes and allow more room for the growth of the new canes. 



Orange Rl:st may ajipear in May or June. It is easily identitied by tlie 

 bright orange color on the under sides of the leaves. There is no 

 method of preventing this trouble. As soon as it is found, the bush 

 should be dug out and burned. If allowed to remain the disease will 

 spread and destroy many plants. Secure disease free i^lants in starting 

 new plantations. 



Anthracnose. a common and troublesome disease especially of black 

 raspberries and blackberries, identified by the grayish spots generally 

 near the bases of the canes. Recent spraying experiments prove the 

 necessity of three aiDplications of lime-sulphur solution to control it, 

 applied — first, in early spring just before growth begins, using 2^ gal- 

 lons, testing 33° Beaume, to 50 of water; second, when the new canes are 

 six to eight inches long, using I14 gallons to 50 ; third, just before 

 blossoming, at the same rate as previous spray. The removal of all 

 grass, weeds and trash in the plant rows, keeping them clean and well 

 cultivated, will help to prevent this disease. 



"Worms" or "Slugs" may appear at any time. Spray with an arsenical 

 if early in the season, but it near picking time, use hellebore or pyretliruni. 

 Cut out and burn gouty galls, tree-cricket eggs and borers in stems. 



GENERAL TREATMENT FOR STRAWBERRIES. 



Examine the young plants before setting thenu Pick ofT all discolored 

 or diseased leaves. If root-lice are suspected, di]* llic roots in strong 

 nicotine solution. 



After the growth starts, spray v.ilh Bordeaux and an arsenical poison 

 to prevent the leaf-spot, and destroy the leaf-roller insect that may be 

 present. 



For fruiting jdantalions, s|)ray with Boi-dcaux before blossoming, and 

 repeat ten days to two weeks lat(M'. After fruiting, if the bed is to Ix' 

 fruited again, mow and burn over (juickly (as (»n a <hiy when thei'e is 

 a wind, to avoid burning the crowns of the plants). If Leaf-rollers 

 have been ])resent in the immediate past, sjn-ay witii poison aflei- the 

 growth has started again, but before the leaves curl.
